Autumn equinox

Autumn is in the air—officially. The September equinox marks the transition from the lush summer to the mellow fall in the Northern Hemisphere, while in the Southern Hemisphere, it signals the beginning of spring. The term "equinox" is derived from Latin, meaning "equal night." During this moment, the Earth"s axis is perpendicular to the sun, meaning it rises due east and sets due west, a rare moment of global balance. This balance occurs because the Earth"s axis is neither tilted toward nor away from the sun.
